Crosnier, L., Drévillon, M., Ramos Buarque, S., and Soulat, F. 2008. Three ocean state indices implemented in the Mercator-Ocean operational suite. – ICES Journal of Marine Science, 65.We present three indices for the state of the ocean, all computed using the Mercator-Ocean analyses and ocean forecast system: an upwelling index based on sea surface temperature (SST), the tropical cyclone heat potential, showing the thermal energy available in the ocean to enhance or decrease the power of cyclones, and the Indian Ocean dipole mode index based on SST. Such indices are updated on a weekly or monthly basis.
